In short : a speckle essentially has a random polarization state at any position, we exploit this to show we can violate a BI.

Matthew McConaughey says he wants a private LLM, fed only with his books, notes, journals, and aspirations, so he can ask it questions and get answers based solely on that information, without any outside influence.

this exists it is called thinking

How on earth did Parisi came up with the idea of an ultrametric space of replicas?

WTF?

Heisenberg on Bohr's occasionally excesssively generous nature. One of the first lessons learnt as a Nature editor about the "fringe" submissions is that this is exactly what will happen if you let it.

Earth-shaking waves from Greenland mega-tsunamis imaged for the first time – Physics World New analysis of satellite altimetry data reveals that trapped waves called seiches were responsible for anomalous seismic signals in 2023

Scientists hide messages in papers to game AI peer review Some studies containing instructions in white text or small font — visible only to machines — will be withdrawn from preprint servers.

4-panel comic. (1) [Person 1 with ponytail flanked by person with short hair and another person speaking into microphone at podium] PERSON 1: In the early 2010s, researchers found that many major scientific results couldn’t be reproduced. (2) PERSON 1: Over a decade into the replication crisis, we wanted to see if today’s studies have become more robust. (3) PERSON 1: Unfortunately, our replication analysis has found exactly the same problems that those 2010s researchers did.

New review! Towards practical applications of radiative cooling by Kaijie Yang, Qiaoquang Gan and colleagues is now online.

Radiative cooling technology can help mitigate high temperatures in the built environment and solar panels, but there are barriers to broader applications.

Böhm’s version runs ~59 min while Currentzis: just 46. That’s 13 minutes faster — ~22% less time. If we break it down:
Introitus + Kyrie: 9:36 → 6:48
Rex tremendae: 3:09 → 1:57
Recordare: 7:00 → 5:45

why the rush? are we geting late anywhere?

Why are we playing classical music faster and faster?

I just heard Mozart’s Requiem live — and it felt way too fast, as usual. Just for fun, I have compared two recordings: Karl Böhm (1971), by far my favorit, and Teodor Currentzis (2011).

The difference in tempo is remarkable: 👇

Böhm’s version runs ~59 min while Currentzis: just 46.
That’s 13 minutes faster — ~22% less time.

Here’s the breakdown:

Great to have @jacopobertolotti.com with us today at @icmm-csic.bsky.social

There have been people less than helpful in my journey here. I wanted to acknowledge those too, bc I know I am not unique in this experience. No thank you to the physics study assoc that made me sing songs about how women couldn't study physics without sleeping with the professor, the day I stepped into university life. No thank you to the 5th year physics student that decided to assign me a stripper name within the first minute of meeting me in the physics coffee corner in my first year. No thank you to the technician that was responsible for onboarding me on the use of the cluster in my third year who raised his eyebrows and asked me if that meant I was some sort of computer girl. No thank you to the senior researcher that sent me utterly inappropriate texts after a conference, then proceeded to apologise months later by telling me they had not been meant for me anyway so no hard feelings remain hopefully And no thank you to him for attending every conference I've been to since. No thank you to the people who told me that it was surprising that I was doing a PhD since I was a girl. No thank you to the man who mistook me for a coffee lady at a conference, and after having to correct him two times that I did not work there, responded with you should consider it. No thank you to the researcher that asked me what I was wearing underneath my outfit during a conference. No thank you to the physicist who declared to a room full of other physicists that biologists don't know how to design an experiment. No thank you to the people who have called me scary instead of strong and intimidating instead of intelligent. And finally, no thank you to the exec board of the TU Delft, whose knee-jerk reaction to being held up a mirror about the social safety at the university, was to sue the party holding up the mirror instead of looking at the problems they highlighted. ... You have made me feel like I do not belong in science & I cannot forgive you for that.

A friend included this anti-acknowledgement section on her PhD thesis. She also added the proposition: “Systematic bullying and undermining of girls and women in STEM starts early on and is the reason why they do not stay in science and related fields.”
Absurd we still need to go through this
